Silent Family Silent Glider M
German ultralight trike motorglider
The Silent Family Silent Glider M is a German ultralight trike motor glider, designed by Helmut Grossklaus and produced by Silent Family of Westerrade. The aircraft is supplied as a complete ready-to-fly-aircraft.
Design and development
The Silent Glider M was designed to comply with the Fédération Aéronautique Internationale microlight category and the US FAR 103 Ultralight Vehicles rules. It features a cable-braced rigid hang glider-style high-wing, weight-shift pitch controls and aerodynamic roll controls, a single-seat enclosed cockpit with a bubble canopy, retractable tricycle landing gear and a single engine in pusher configuration.
The aircraft is made from composites, with its double surface rigid wing mounted with the pitch control bar though a slot in the bubble canopy. The pilot seating position is reclined. Various rigid wings can be used and the typical one has a 14.0 m (45.9 ft) span. The powerplant is a single cylinder, air-cooled, two-stroke, 28 hp (21 kW) Hirth F33 engine or, optionally, a Geiger or Flytec electric motor, powering a two-bladed folding composite propeller. With the Hirth engine the aircraft has an empty weight of 118.5 kg (261 lb) and a gross weight of 231 kg (509 lb), giving a useful load of 112.5 kg (248 lb). With full fuel of 22 litres (4.8 imp gal; 5.8 US gal) the payload is 97 kg (214 lb).

Why this record matters

Named sources, stable identifiers and responsible institutions provide the strongest route from overview to verifiable evidence. The source revision retrieved here is dated Nov 9, 2025. The linked authority identifier is Q5610593. 1 of 1 selected statements include explicit references; 0 carry qualifiers and 0 use preferred rank.
Overview language is designed for orientation and should not be treated as a substitute for the evidence cited beneath it. The lead is largely declarative, so disagreement and counter-evidence require a deliberate search beyond the opening account. Authority statements aid reconciliation but still require their own references, qualifiers and ranks to be checked.
